"Hi Tridge,
Are there any caveats with using this release on the older APM1.4 hardware?

Thanks,
Dave"

"Hi Tridge,
Some receivers (such as frsky D4R-II and D8R) output rx RSSI as PWM on one of their regular servo output pins (once the rx has been put into PPM mode, freeing the pins up), would it be possible to support such receivers?

e.g. if RSSI_PIN…"

"Hi,
Note that when you connect an MTK GPS (with DIYDrones firmware) to an APM, the APM instructs it to switch to a more compact binary protocol rather than NMEA and the output stream will no longer be legible in a serial console. It's possible that…"

"Hi Dirk,
It's probably "Servo Pitch PID" that is too high.

However,
I'd suggest you may wish to reset the arudupilot and start again with the default settings following this page to tune the PID's in:…"

"Hi,
Mode 6 is not changeable because at that setting (>1750ms PWM pulse-width), a hardware manual override is invoked and chan 1-4 are passed straight to the servos and not into the APM at all. I understand this is done within the PWM encoder,…"

"A quick look at Attitude.pde suggests that the servo pids *do* need re-tuning as the servo output is scaled based upon what speed info the APM has.
When there is no airspeed sensor, it uses the throttle servo output as an indicator, when there is an…"
